Problems solved by technology

Such devices are particularly difficult to operate because the lock lever must be pressed and held while another lever must be pressed to ignite a piezoelectric unit which ultimately lights the device.

Embodiment Construction

[0015]In one application, a torch can be advantageously used by campers to start campfires, and for a variety of other uses and activities. The torch can provide more robust combustion power in a durable, compact form that permits a camper or other user to position a jet flame at any angle during use, even in windy conditions.

[0016]Generally, wherein like numbers describe like parts, FIGS. 1-7 illustrate a torch 10 that includes a fuel delivery system, an ignition system, and an interlock mechanism. In one particular aspect of the invention, the interlock mechanism prevents the ignition system from igniting fuel delivered from the fuel system, while preventing the delivery of fuel through the fuel system to one or more microjet burners. More specifically, the interlock system is a physical mechanism that prevents an ignition button from opening a fuel discharge valve that allows gas to flow, and ensuring that the ignition button does not actuate a piezoelectric ignitor (not shown, t...

Abstract

A torch device having a pivoting torch arm, including a fuel delivery system having a fuel tank and microjet burners positioned in the end of the torch arm, and an ignition system including an ignition button and a piezoelectric igniter for igniting fuel, and an interlock mechanism including a mounting tab pivotally attaching the torch arm to the body of the torch, with a guide pocket defined by a laterally-extending wall of the mounting tab, and a rocker arm having a distal arm cooperating with and confined within the guide pocket, and a proximal arm cooperating with the ignition button, and configured to prevent a user from pressing the ignition button based on the angular position of the torch arm relative to the torch body.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 502,927, filed May 8, 2017, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The invention relates to portable fuel torches.BACKGROUND OF THE INVENTION[0003]Known hand-held, gas-burning devices include those that incorporate child-safety features to at least inhibit inadvertent ignition of the gas-burning device, for example, by a child. Known lighters include those having an upper cap, or cover, which can be “flipped” open to use the lighter, but does not automatically return to the non-use, closed position.[0004]Known devices further include a particular type with a lock lever that squeezes a gas pipe to cut the gas supply and quench the device. Such devices are particularly difficult to operate because the lock lever must be pressed and held while another lever must be pressed to ignite a piezoelectric unit which u...
